Title: Improvements relating to the forming of hollow plastic articles
IPC: B29C48/09
Filed: 1955-03-03
Abstract: 809,534. Moulding hollow plastic articles. OWEINS-ILLINOIS GLASS CO. March 3, 1955 [March 3, 1954], No. 6345/55. Class 87(2). Plastic material, after having been fed into an annular cavity under the pressure of a supply source until the cavity is full, is exposed to another pressure to mould a finished portion of a plastic article at an annular open end of the cavity, and that finished portion is moved away from the cavity end while a tube integral with it is extruded by means of the original pressure, i.e. that of the supply source, and the moulding and extrusion steps are repeated. In one form, Figs. 1-4, plastic material is forced through a channel 24, Fig. 1, into a tubular cavity 23 formed between a sleeve 20 and a mandrel 22. Then a tubular plunger 25 is raised to the Fig. 1 position, thus segregating the plastic material in cavity 23 from the main body of plastic material in channel 24. The plunger is then raised to the Fig. 2 position to force material from the cavity into a mould 26 to form the neck of a hollow plastic article. Then the plunger descends, Fig. 3, and pressure from channel 24 forces material in tubular form T, Fig. 4, out of the cavity, the moulded neck being integral with the upper end of the tube T. The plunger rises again, to the Fig. 4 position, to isolate the cavity, and a knife 31 cuts away the tube. The neck mould is again positioned as shown in Fig. 1 and the process is repeated. Tubes thus made are blown to hollow form, Fig. 6. In a modified apparatus, Figs. 7 and 9, the plunger 25 is rotatable and has a groove 32 which may be positioned to isolate the cavity from the passage or join them, In a further modification, Figs. 16 and 17 (not shown), one passage may feed two cavities. Specification 758,299 is referred to.

IPC: F42B12/66
Filed: 1916-05-04
Abstract: 105,978. McGill, J. F. May 4, 1916. Projectiles; projectiles, making.-Relates to explosive shells divided into a number of superposed radial chambers for containing chain shot, and consists in the combination of means for dividing the shell into radial chambers for effecting the tangential discharge of chain shot with means for selectively varying the tangents on which the chain shot are discharged. In the form shown in Figs. 2 and 3, the shell is divided into four transverse spaces A, B, C, D by disks 36, and each space is divided into four chambers bv crosspieces 35 interlocking with lugs on the disks 36. These chambers are filled with chain shot 39, 40, and are surrounded by a cylinder 20 made in four segments provided with external ribs 21 engaging grooves in the shell body 17, and with internal grooves 28 engaging the cross-pieces 35. The chain shot are held in the chambers bv bent lugs 41 on the disks 36, and sometimes also by separate segments. All these internal fittings are clamped between the base 15 and the nose 16 of the shell, a cruciform disk 34 being interposed between the base 15 and the chambers. The disks and crosspieces are perforated, and passage ways 27, 25, 24 are formed in the base and through and around the cylinder 20 to lead into the chambers the gases of explosion from a bursting charge 29 situated in the nose of the shell, thus to ensure the dispersion of the chain shot. The fuse tube 18a extends well into the charge 29 to prevent the chocking of the passages 24 with unburnt powder, The chambers of the various sections A, B, C, D can be arranged at various angles relatively to each other according to the grooves 28 selected for the cross-pieces 35, and the shot 39 can be arranged within the chambers at various radial distances from the axis of the shell to cause the chain shot to spread in various tangential directions and at various speeds. In order to facilitate the loading of this shell, the internal fittings are assembled in upright position over a rod 42, Fig. 11, above a disk 44a which, together with the cruciform disk 34, is screwed to one end of the rod 42, and a disk 44<x> with a sleeve 45 is clamped against the chambers by a disk 44 which is screwed to the other end of the rod 42. The device is then turned on its side, resting on the edges of the disks 44, 44a, which are larger than the rest, and the chain shot are put into the chambers and locked therein. Then the disk 44a is removed, the device is inserted into the shell within the cylinder 20, and the rod 42 is unscrewed from the cruciform disk 34 and removed with the disks 44, 44<x> and the sleeve 45.

Title: Improvements in or relating to ice making method and apparatus
IPC: F25C1/12
Filed: 1950-03-17
Abstract: 673,145. Ice-making. FLAKICE CORPORATION. March 17, 1950 [March 26, 1949], No. 6710/50. Class 29 Water is flowed by gravity in a thin layer over the freezing surfaces of an icemaking machine at a rate greater than the maximum rate of freezing, the unfrozen water being recirculated, and part of this water being discharged and replaced by additional water to limit the concentration of dissolved salts. The invention is shown applied to the apparatus described in Specification 669,494, comprising banks of freezing tubes 3 cooled by evaporators 10 and supplied with water to be frozen from a sump 20 by a pump 26, pipe 30 and header 32. The water freezes on the inside surfaces of the tubes, excess water returning to the sump which is supplied with water by a pipe 22 and float valve 24. When the hole through the centre of the ice is reduced to a predetermined size the water passes through a pipe 80 on to a thermostat bulb 76 so that a switch 52 opened is deenergizing a solenoid 54 which through a line 62 opens a solenoid valve 64 in a byepass pipe 66 between the condenser 8 and the evaporator 20 so that hot refrigerant vapour is supplied to the evaporator to release the ice, which falls from the freezing tubes. Release of solenoid 54 also, through a line 58, opens a valve 38 in the pipe 30 to withdraw water from the sump to waste. After a predetermined time a delayed-action solenoid 68 operates to stop the pump 26 and start an ice-cutter motor 72. When, all the ice has been discharged from the tubes 3 a thermostat 74 closes a relay 50 to re-energize the relay 54, and the thermostat 76 closes the switch 52 so that a new cycle is commenced. The amount of water withdrawn from the sump may be controlled by adjusting the time delay 68 or the opening of the valve 38. When clear ice is not required the opening of the valve 38 is prevented by breaking a switch 60. In a modification a small flow of water is continuously bled away from the sump in heat-exchanger with the entering feed water and controlled by a valve. Specification 669,467 also is referred to.

Abstract: 1375925 Cathode-ray tube circuits ROBERT BOSCH FERNSEHANLEGEN GmbH 16 Feb 1972 [17 Feb 1971] 7159/72 Heading H4T When the level of a television signal as measured at the output of amplifier 5 (Fig. 1) reaches a value at which a Zener diode 11 conducts a pulse developed across a resistor 14 so biases diode 16 that beam current for the signal electrode 2 of the pick-up tube 1 is now supplied via diodes 16 and 18 so that the potential across the load resistor 6, which provides the signal input to amplifier 5, remains constant despite increase in the tube beam current. The invention is concerned with colour television cameras employing pick-up tubes operation with low level beams current (e.g. Plumbicon, RTM) in which, to prevent the occurrence of "comet-tail" effects (e.g. in rapidly moving scenes) the beam current is increased during fly-back intervals and the storage target of the tube scanned to discharge those portions containing highlights. During this operation enhanced signal currents of approximately 500 times the normal signal level may occur and without the limitation provided by the prevent invention amplifier 5 would "ring" and prevent the transmission of useful picture signals. The latter which are supplied over path 8 to an output 9, are integrated by means of resistor 19 and capacitor 20 and supplied via impedance transforming transistors 21, 22 to a transistor switch 24 which is made conductive by line flyback pulses at 25 so that line 9 assumes a level which is dependent on the mean amplitude of the preceding picture signal. Instead of the arrangement of diodes 16 and 18, a similar effect may be obtained by employing the Zener diode generated pulse to control the source-drain path of a field effect transistor shunting the impedance 6 (Fig. 3, not shown).
